Biosphere 2 ~ where science lives

 Discover Biosphere 2, do you know what Biosphere 1 is?

Biosphere 2 is located north of Tucson, Arizona at the base of the stunning Santa Catalina Mountains. This one-of-a-kind facility sits on a ridge at a cool elevation of nearly 4,000 feet and is surrounded by a magnificent natural desert preserve. Come experience the remarkable Biosphere 2 which Time Life Books named one of the 50 Must-See Wonders of the World. See why visitors from around the globe journey here for this unique adventure not found anywhere else. Discover real-time research on the future of our planet as it unfolds in the world’s largest earth science laboratory.

The Biosphere 2 visitor center houses exhibits and multimedia displays along with a bookstore and cafe. Should you choose, your experience at Biosphere 2 is facilitated by an expert interpretive specialist who takes you inside and under the glass. The beautiful trail system takes you along a once-in-a-lifetime tour route of the 3+ acre research facility where you will smell our ocean and feel a tropical rainforest up close. In addition to escorting you through the upper biomes, your interpretive specialist takes you through the basement technosphere and into one of the amazing lungs that helped moderate air pressure in Biosphere 2’s once-sealed environment. Your tour can include the underwater Ocean Gallery where you can explore the million-gallon ocean and its research value – including coral reef resilience. Before or after your guided tour, take time to enjoy the many different exhibits, programs, and events that are offered all season. The visit and guided tour provides an opportunity to appreciate and discuss important science in a friendly, informal setting. Your experience will be like no other!
